As mentioned in my previous post, all plugins need an update to function in QGIS master – soon to be 2.0. The OpenLayers plugin is one of the most popular plugins but so far has not been updated by the developer. If you miss it, you can get a fixed version from qgis.nl Temporary Fix …

Recently, @simo has posted an elegant solution for defining custom styles for Google Maps layers in OpenLayers on gis.stackexchange. An example with source can be found at http://www.empreinte-urbaine.eu/mapping/styled_gmap.html. The idea seems to be to use a StyledMapType: The StyledMapType allows you to customize the presentation of the standard Google base maps, changing the visual display …

There are many nice examples out there of how to use a getFeatureInfo request in OpenLayers to display a feature’s attribute table. In some applications it can be useful though not to display the full attribute table but to only select one attribute value from it and output it somewhere, e.g. in a text field. …

There is a new layer class in OpenLayers API: OpenLayers.Layer.WMS.Post [1]. – Great work! While the “normal” OpenLayers.Layer.WMS class requests maps via HTTP GET, this new class sends the request via HTTP POST. This way, we can now send big client-side created SLD files in our GetMap requests that used to exceed size limits of …

In a previous post, I showed how to use docker to run a single application (GeoServer) in a container and connect to it from your local QGIS install. Today’s post is about running a whole bunch of containers that interact with each other. More specifically, I’m using the images provided by Geodocker. The Geodocker repository …

We are looking forward to a hot geo summer here in Central Europe with both the German FOSSGIS (this year in conjunction with the annual AGIT conference) and the international FOSS4G just a few weeks away. It’s going to be exciting, and I still have a lot of talks (and a keynote) to prep for …

In Publishing interactive web maps using QGIS, I presented two plugins for exporting web maps from QGIS. Today, I want to add an new member to this family: the qgis2web plugin is the successor of qgis-ol3 and combines exports to both OpenLayers3 as well as Leaflet. The plugin is under active development and currently not …

In my opinion, Stamen’s Toner-lite map is one of the best background maps to use together with colorful overlays. The only downsides of using it in QGIS are that the OpenLayers plugin can not provide the tiles at print resolution and that the projection is limited to Web Mercator. That’s why I’ve started to recreate …

Stamen’s maps are amongst the most creative and beautiful OpenStreetMap visualizations and it would be great to have them as base maps in QGIS. No problem! Nathaniel Kelso has already done all the work for us and we can download the extended OpenLayers plugin from his Github page. (There is a pull request in place …
